Application November 9, 1944, Serial No. 562,645

1 Claim. l This invention pertains to special receptacles nd packages, and more particularly to a circular ox type container or holder especially adapted to nterchangeably enclose an original package of tactics or analogous products, including finely nuted materials such as face powders.

l powders and the like are commonly packaged in aper drums or circular boxes which are frail and easily distorted or crushed, and which are of purely utilitarian character, upon which little or no effort is expended to render them of attractive or pleasing appearance. While efforts have been made to provide containers of metallic or molded plastic construction, such devices usually have been too expensive and too bulky. This is particularly true of telescopic containers of molded plastics, wherein due to double overlapping walls the use of excessive quantities of material are necessitated.

In the present instance there is contemplated a protective holder or enclosure, which may be of ornamental appearance, preferably of molded plastic material, within which different commercial paper powder drums or manufacturers containers are interchangeably engageable. Such holder comprises top and bottom sections telescopically engageable with the manufacturer's stock paper drum. The sections abut one upon the other or upon an intermediate projecting peripheral band of the paper drum. The paper drum is detachably engageable within the holder in such manner as to seal the drum against leakage, and also to reinforce or stiffen its walls against crushing pressure or distortion,

The object of the invention is to improve the construction as well as the means and mode of operation of receptacles or containers, whereby they may not only be economically manufactured, but will be more efficient in use, capable of interchangeably receiving therein conventional paper drums, be of strong and sturdy construction, and.

unlikely to get out of repair.

A further and impor ant object of the invention is to provide an enclosure device which is capable of interlocking engagement with an enclosed paper drum to reinforce and stiffen the drum to enable it to resist deformation pressures, and which will seal the drum against leakage.

A further object of the invention is to provide a hard and resistant enclosure or holder for a commercial powder drum which is of pleasing appearance and ornamental character, durable and water-proof and which will not swell or shrink under influence of atmospheric change.

A further object of the invention is to provide a holder for a conventional cosmetic or face powder container, or the like, possessing the advantageous structural features and inherent meritorious characteristics and mode of operation herein set forth.

With the above primary and other incidental objects in View as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or illustrated in the accompanying drawings.

In the drawings, wherein is illustrated the preferred but obviously not necessarily the only form of embodiment of the invention,

Fig. l is a side elevation, partly broken away, of a container or receptacle embodying the present invention, enclosing a conventional commercial face powder drum.

Fig. 2 is a side elevation of the component parts of the assembly shown in Fig. 1 in disassembled relation.

Fig. 3 is an enlarged detail sectional view of the several parts in assembled relation,

Fig. 4 is a side elevation partly in section illustrating a modification.

Fig. 5 is a detail sectional view of a further modification.

As heretofore mentioned, the present invention pertains to an enclosure or receptacle in which is received a conventional paper drum in which cosmetics and analogous products, especially face powder, are originally packaged by the manufacturer.

Such drum ordinarily comprises a cylindrical paper shell I open at its bottom for filling purposes, and having a thin membrane 2 of paper or other material, usually of transparent character, overlying and closing its top In practice the manufacturer fills the drum through its open bottom with face powder or other commodity, while the drum is in inverted position. Thereafter a pressed paper cap or other closure is secured over the open bottom and the drum is reversed with the thin paper closure 2 uppermost. The purchaser breaks the paper cover 2 to afford access to the contents. The paper shell I lacks the necessary strength to resist distortion and crushing pressures. Also, being paper if the package is deposited upon a wet or damp surface, it will absorb moisture, causing deterioration of its contents and disintegration of the paper drum.

The present protective enclosing receptacle comprises a top section 3 and a bottom section 4,

preferably, but not necessarily, molded from plastic material, both of which are telescopically engageable with the manufacturers original package or drum I. The bottom section 4 is detachably engageable with the drum i and may be utilized in lieu of the customary closure or cover ordinarily applied to the bottom of the drum after filling.

The bottom section 4 is provided with an interior annular grooved depression 5 at the juncture of the bottom and side wall of the section 4, into which the bottom margin of the annular wall of the paper drum I projects, and which forms a trap to prevent escape of the contents of the drum. The grooved depression 5 is of such size that the bottom margin of the drum snugly fits the inner surface thereof. The bottom section thus reinforces the paper wall of the drum and resists external pressure by which the drum may be distorted or crushed. To draw the margin of the drum i to a tight seat within the annular channel 5 of the bottom section 4, the interior of the side wall of the section 4 is provided with an integral molded helical bead 6 simulating a screw thread. This bead may extend through several complete turns about the interior of the section 4, but for convenience of molding and stripping operations it preferably comprises but a single turn.

Projecting from the external face of the wall of the drum I is a mating head 1, which is preferably pressed directly in the material of the drum wall by a rolling operation, but may be otherwise formed in a separate strip or band adhesively secured to the exterior of the drum wall, as shown in Fig. 6. The interengaging helical beads ES and I do not necessarily extend into radially abutting relation with the opposing surfaces, but may have peripheral clearance therebetween to provide greater manufacturing tolerances. The beads 6 and I have lateral contact one with the other to relatively draw in the bottom section 4 and the enclosed drum I into tight seating engagement within the annular channel 5. To insure a leakproof seating contact, the bead 5a defining the channel 5 is convex, whereby it exerts a slight radial camming action tending to expand the lower margin of the drum I to insure a leak-tight joint. The bottom margin of the drum I is drawn by the coaction of the beads 6 and I against the bottom of the channel 5 to further seal the joint. In lieu of such interlocking engagement, the bottom section 6 may be made with sufficiently tight fit to retain its engagement with the drum I by frictional contact.

The cap shaped top or cover section 3, which preferably is also of molded plastic material, has telescopic sliding engagement with the top area of the wall of the drum I into marginally abutting engagement with the top of the wall of the bottom section 4, as shown in Fig. 1. However, to economize molding material and afford an attractive ornamental appearance, the drum I may be provided with a peripheral band 9 of less width than the height of the drum, the opposite edges of which afford stop shoulders or rabbets I0 against which the margins of the peripheral walls of both the cover section 3 and the bottom section may abut, as shown in Fig. 4. The peripheral band 9 may be of distinctive color or may bear ornamental delineations or indicia which supplement the ornamental appearance of the molded plastic top and bottom sections 3 and 4. The latter may be of ornamental design, or may bear surface ornamentation or color characteristics, to enhance their appearance.

The cover section 3 and the upper portion of the drum I may be provided with interengaging 5 helical beads 6 and I, as in Fig. 5, substantially duplicating the beads 6 and I, by which the bottom section 4 is detachably engaged with the drum. By a partial rotary motion of the cover section subsequent to an initial telescopic adjustment, the cover can be forcibly drawn into tight sealing engagement with the drum. However, the cap or cover section is preferably devoid of an interior bead 6' and is telescopically engageable with a plain slip fit upon the upper area of the enclosed drum I.

The interior of the slip fit cover section 3 is preferably, but not necessarily, provided with a series of interiorly circumferentially spaced pads or thickened areas II upwardly spaced from the margin of the top section, which frictionally engage the periphery of the drum I more tightly to prevent displacement. Due to the thinner mar ginal area, its initial telescopic engagement Wit the drum is quite easy but becomes tighter as th pads II slidingly engage therewith. The lower margins of the pads II are preferably beveled to facilitate their sliding frictional contact. For packaging face creams, ointments, and other analogous commodities, which are usually packaged in jars, there is shown in Fig. 5 a somewhat modified construction, wherein the commodity may be originally packaged by the manufacturer in a cardboard drum Ia, having a helical bead or corrugation la rolled or pressed in its top margin similar to the thread or bead I at the bottom of the drum. The base section 4 is substantially the same as that before described. The drum Ia may, if desired, be provided with a medial peripheral band 9, such as is shown in Fig. 4, or may be devoid thereof, as illustrated in Fig. 5. The cover section 3a is provided with an interior thread or bead 6a for engagement with the bead or corrugation Ia. The top section is further provided with a seating groove or channel 5a within which the top margin engages under thrust pressure, sufliciently to afford an air tight joint. It is customary to provide jars and similar containers with a lining disc of paper between I the lid and receptacle as a gasket. In the present instance the drum being of paper cardboard, which being sufficiently compressible makes a direct contact under thrust pressure against the bottom of the seat channel 5a. to form a leak-tight joint and performs the function of a liner or gasket, and eliminates the necessity thereof. The same result is produced by the thrust pressure of the bottom margin of the drum I in the seating groove 5.

The molded top and bottom sections readily 60 lend themselves to distinctive ornamentation by variation of exterior shapes and surface contours and by surface design and color variations.

The enclosure protects and reinforces the original drum package, and prevents injury thereto 5 and leakage of its contents.

In the use of powder containers or drums having transparent covers, it is found that during shipment, the shaking and vibration causes the powder contents to settle and compact, leaving vacancies in the tops of the packages. This is true notwithstanding that the packages initially may have been completely filled. Such condition is unsightly and highly objectionable to dealers, and causes considerable sales resistance. I 75 The present construction tends to overcome such,

objection. The present container or drum is filled from the bottom and the contents heaped to afford an ample excess of material which is then placed under pressure sufificient to initially compact the powder by application of the screw threaded bottom element. As the bottom is rotated into place, screw pressure is exerted on the contents in an axial direction, which distributes the powder, and fills all voids and compacts the contents to such degree that the subsequent handling will not cause further settling. and compaction, or cause vacancies in the tops of the packages. The contents having been thus initially compacted under pressure when the package is filled is not likely to again become loose but will preserve its initial full appearance.

While the top and bottom elements are preferably made of molded plastic material, as a matter of fact such elements may be formed from sheet metal with an inturned screw threaded flange for engagement with the threaded peripheral areas of the paper drum. Such sheet metal elements may also be provided with a concentric depression affording a grooved seat for the marcf the drum, said seat having an inclined 'rface which will exert expanding pressure Within the margin of the drum as screw pressure is applied by rotation of the bottom element.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into efiect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claim.

Having thus described my invention, I claim:

A receptacle for enclosing a packaging paper drum container having an open bottom comprising a plastic base section, including a bottom and an upstanding peripheral wall thereon, an interior annular seating groove adjacent the bottom of the base section in proximate relation to the interior of the side wall thereof to receive therein the bottom margin of the enclosed paper drum, interengaging conformations upon the exterior of the enclosed drum and the interior of the vertical peripheral wall of the receptacle for drawing the margin of the drum into seating engagement within the annular groove, upon relative rotation of the drum and peripheral wall, the interior engaging formation on the receptacle wall terminating in said annular seating groove, said paper drum extending upwardly beyond the free edge of the peripheral wall on said base section and a telescopic cover section engagcable with the upper portion of the side wall of the drum and with the free edge in abutting engagement with the peripheral wall of the base section.
